3.1 PC6 Particle Counter 39
3.1.3.3 Mounting
The total space needed to mount the PC6 Particle Counter sensor is an area 533mm (21 in.) wide
and 1016mm (40 in.) tall. The PC6 Particle Counter should be permanently mounted to a flat, vertical
surface, such as a wall or support column, in an upright position using the 4 mounting holes located
on the enclosure. The mounting hole dimensions are 187 mm (width) and 87mm (height) and the
mounting holes have a diameter of 3.9mm. The weir should be mounted as shown next to the PC6
Particle Counter, utilizing the mounting clamps, with the weir height adjusted so that the top of the weir
is approximately 254mm to 305mm ( 10 - 12 in.) above the top of the PC6 Particle Counter. The weir
assembly and PC6 Particle Counter should be mounted at an elevation sufficient to achieve overflow
at minimum source pressure. A ball valve can be used to regulate the flow into the weir assembly.
